Description

At the bottom of the on-slip shoes

Technical field

The present invention relates at the bottom of the on-slip shoes.

Background technology

For example paying attention to ground such as sanitary food processing factory, for the ease of cleaning, very level and smooth corrosion resistant plate is used on its ground mostly, ground under the situation of being drenched, become by water or edible oil be prone to sliding.On-the-spot for such work, use to ground surface be provided with concavo-convex design guarantee slip resistance most be difficult.Therefore through the design of sole being guaranteed slip resistance just becomes necessary.

According to above-mentioned explanation, in recent years, can tackle the ground of being drenched by water or wet goods liquid have excellent slip resistance can on-slip shoes at the bottom of exploitation extremely expect.

The anti-sliding design of sole can be divided into two kinds haply.A kind of is to be level and smooth shape to the landing ground that the Design Module of sole becomes each module (projection lands); And the structure that the side of this landing ground and module (facade) intersects vertically (for example Fig. 3 of patent documentation 1 and Fig. 4), a kind of in addition is to be the landing ground that Design Module becomes each module the structure that has trickle concavo-convex matsurface.

Undoubtedly; If the frictional force between the landing ground of ground of drenching and sole is high; Be to be difficult for sliding; Before a kind of structure be through not forming fluid film between the contact interface that makes landing ground (sole) and ground, thereby a kind of structure in back is through making fluid improve above-mentioned frictional force respectively from the method that contact interface discharges.

Summary of the invention

The problem that invention will solve

But; With landing ground be designed to level and smooth shape before a kind of design (content of the structure that above-mentioned communique is put down in writing) can obtain higher coefficient aspect the dynamic friction; But aspect static friction, can not expect higher numerical value; This after all design can make slide to be interrupted promptly stopping easily, but in walking, and the control when beginning to slide when landing is difficult.In contrast; The situation of the matsurface that the back is a kind of can expect to obtain the antiskid function of static friction aspect; But can not expect to obtain the antiskid function of dynamic friction aspect, the coefficient of friction of therefore hoping dynamic friction and static friction to occur is all at the bottom of the on-slip shoes of the excellence of the non-skid property more than the benchmark numerical value.

The present invention is exactly response to this.

The means of dealing with problems

At the bottom of the on-slip shoes; It is characterized in that: the elastomer by rubber or thermoplastic resin is processed; Design module on it is provided with by the arrangement of a plurality of front and back, the separate jut that lands constitutes; There is landing ground in the said permission gap that existence can produce strain between the jut that lands on the said jut that lands, the even surface of the front and back that said landing ground lands when moving simultaneously and between this even surface by countless concavo-convex and matsurface that form is formed; Said concavo-convex protuberance and said even surface land simultaneously, and the side of the said jut that lands and this landing ground 3 are perpendicular.

The effect of invention

In the present invention; Because when walking lands; The even surface of the front and back on the landing ground of sole and the protuberance that is present in the matsurface between this even surface can land simultaneously (kiss the earth); Even so slide, contact the inhibition slip with ground thereby the protuberance of matsurface also can pass fluid, and can obtain sufficient confficient of static friction because of even surface contacts with fluid to produce.In addition; When moving; Move owing to even surface is equivalent to cut off fluid, thereby not only the fluid between even surface and the ground is excluded, the fluid in the matsurface also is rejected to the outside of the jut that lands through the gap between the protuberance; Can not produce the slip that the existence owing to fluid causes, therefore the sole with excellent skidproof effect can be provided.

The specific embodiment

Accompanying drawing is represented the specific embodiment that the present invention is correlated with; Fig. 1 is the front view of sole, and Fig. 2 is the plan view of Fig. 1, and Fig. 3 is the partial enlarged view of Fig. 2; Fig. 4～Fig. 6 is the front view of other embodiment, and Fig. 7 is the zoomed-in view of the jut that lands of other embodiment.

Sole A of the present invention is made up of the elastomer of processing with rubber or thermoplastic resin; On the surface of sole main body 1 design module 2 is arranged; Design module 2 by a plurality of front and back arrange the jut 2a that lands that be provided with, separate ... 2b ... constitute; There is the permission gap that can produce strain (compression) in the said jut 2a that lands between the 2b.

On the said jut 2a that lands landing ground 3 is arranged, said landing ground 3 is by the relative even surface 3a that is positioned at both sides, 3a and between this even surface 3a; Matsurface 3b between the 3a forms; Make the above-mentioned even surface 3a of the both sides that are positioned at the matsurface 3b on the said landing ground 3,3a is in the zone of land simultaneously in the time of can making its walking (landing) (kiss the earth), and; Jut 2a lands; The side of 2b (facade) 2a ', 2b ' are with respect to this even surface 3a, and 3a is vertical (even surface 3a, 3b and side 2a ', 2b ' are the setting of the direction that intersects vertically each other).

Matsurface 3b is provided with countless concavo-convex, the protuberance 3b ' that this is concavo-convex ... with above-mentioned even surface 3a; When 3a lands simultaneously; This protuberance 3b ', the gap between the 3b ' becomes the path of fluid (normally oil), is related to fluid removal to the outside of landing ground 3 (according to the measurement of roughmeter; This is concavo-convex to be 3.0～40 μ m, preferred 10～40 μ m).

In addition; Matsurface 3b as shown in Figure 3 at even surface 3a, is designed with recessed depressed part 5 between the 3a; The bottom surface of this depressed part 5 is matsurface 3b; In the time of even surface 3a kiss the earth, the part of matsurface 3b is protuberance 3b ' ... can not be driven plain from depressed part 5 outstanding landing, therefore positively form the gap as aforesaid fluid passage.For instance; The situation of matsurface 3b as shown in Figure 7, protuberance 3b ' ... summit and even surface 3a also can form the gap when being in same plane, when sole lands; Fluid is rejected to outside the landing ground 3 from matsurface 3b through this gap; Though compare as the situation of matsurface with above-mentioned bottom surface with depressed part 5, can't deny the low of its performance, the situation that is higher than even surface 3a with matsurface (recess of matsurface) is compared; Its confficient of static friction increases, so can not say that the embodiment of structure of matsurface 3b as shown in Figure 7 of the present invention is bad.

The sole of embodiment 1 as shown in Figure 1; Design module 2 is by its even surface 3a; 3a is a plurality of jut 2a formations that land that fore-and-aft direction is arranged on sole A (footwear), each length that lands jut 2a is equivalent to the transverse width of sole A, thereby makes design module 2 be the structure of striated.Because each jut 2a that lands foregoingly arranges on the fore-and-aft direction of sole A, so can play anti-skidding function respectively during walking.Like Fig. 4～shown in Figure 6; Design module 2 is made up of with the jut 2b that lands the jut 2a that lands, the even surface 3a of the said jut 2a that lands, and 3a arranges according to the fore-and-aft direction of sole A (footwear); The even surface 3a of the said jut 2b that lands; 3a arranges according to the left and right directions of sole A (footwear), stretchs out at pin and waits and when making pin laterally mobile, the existence of the jut 2b that lands can be played skidproof effect.
